Proximity sensor issues - LG G5 Questions & Answers

Hi,
I've just had my screen replaced on the LG G5. However, post screen replacement I am facing the following problems:
- As soon as I dial a number the screen goes black and locks itself. I need to press the button at the back to unlock the screen.
- If i make a call using whatsapp, as soon as I hit dial the screen locks itself
I checked and it looks like my proximity sensor is not working. In the apps that I use to test it, it either just reads '0" for the proximity sensor or "NEAR".
Anyone else faced similar issues or have a solution?

I just had my screen/frame replaced and am having the same problem. Tap to wake rarely works and while making a call the display stays on while phone is to my ear. Did you find a fix?

I fixed my problem doing some Googling. I can't post the link to the thread but Google "LG G5 Proximity Sensor Reddit mobile repair".
"I had a similar problem. I replaced my display/frame myself and the tap to wake function rarely worked and the phone display would stay lit when held to my ear. Following the advice here, I found that there was a rubber grommet around the prox sensor window on the old screen that I hadn't transferred over. It's very hard to see and almost looks like it is molded into the frame. I dug it out with some tweezers and transferred it over and it is back to normal."

[Q] xperia mini pro screen bkackout!need help!

I currently using xperia mini pro sk17i,and also using cyanogen 2.3.7 ver.but my phone screen will blackout and unable to turn on whn i made a call.kindly tell me what the problem and how can i fix it.thanks alot!!
looks like bug in proximity sensor.
Hahahahaha!i fixed it!and that was easy!!took me a whole day fot this!!thanks alot dude.XD
what was the resolusion?Im running stock rom and have same bug sometimes.
Probably screen protector (or, dunno, dirt?) bloquing both proximity sensors, thus the phone thinks you have the screen at your ear, so as soon as this function is activated (a call is made or received) the screen turn off.
Easy check, go to services menu (dial *#*#7378423#*#*, go to "Service tests" and then "Proximity switch".
If its ON the whole time, the sensors thinks something is near the screen, it should turn ON only if you cover the sensors (located at the upper left of the screen, beside the speaker), and off if you uncover it.
If no screen protector or dirt is found there, maybe its a software issue (custom ROM), but on stock it should work, else probably a faulty hardware, take it to repair.

Phone unresponsive during call

Hi!
I have a peculiar problem with my Lumia 920. During a phone call the screen is black and unresponsive. I can't hang up, and I always have to wait for the other person to do so. Then after 5-10 seconds, it wakes up and I see the call log. If I quickly tap the sleep button I see the ongoing call screen for a split second.
Any ideas why this may happen? Is it happening to you? I'm on Portico.
did you use any screen protectors? this can happen when proximity sensor is blocked or malfunctioned...
also on black AT&T Lumia noticed gap between case and front camera and dust can enter and "broke" proximity sensor http://wmpoweruser.com/nokia-lumia-920-front-facing-camera-and-proximity-sensor-dust-fix-on-the-way/
also some people notice if press top left corner of phone temporally fix proximity sensor
This is because of Portico! After u update to 1308/1314 the issue will be fixed!

@#&* that proximity sensor

Proximity sensor is supposed to turn the screen off when held to your face, though I have yet to see it do that. On my phone the proximity sensor turns off the display every time I make a call or play a voice mail. This is really annoying, I almost hold the phone to my face, I have headphones, and sometimes I have to do a battery pull to end a call, and forgot about accessing other information on the phone while on a call.
I have found a patch that works with limited success by use of a startup script which resets the sensor, but it's not reliable. I understand that this is a bug in cm10,and I am running pacman based on cm10.2
Does anyone know of any other solutions? Like can I just turn it off? My old phone had no proximity sensor and accidental button presses were rare.

It works. Mine is set to 100 on top and 0 on the bottom. I don't know what both of them do, but those values work for me. Haven't touched the app since first use, it sets on boot automatically.
thank you. i will benefit from this greatly

[Q] screen turns off when touching sensor next to front camera

hi all
i have spent almost 2 days for an answer , no luck
my problem is
my phone s3 lte . screen turns of as soon as i obstruct the front camera and the 2 sensors area . it was ok before , since few days it started doing this . now i cant take screen shot pictures by moving my palm across the screen for example , not sure what this is due to
any help please .?
You've posted in the wrong section, questions go in q&a section -those for the i9305 stand more chance of a reply that won't brick your phone in the special q&a for LTE phones.
Report your own post and ask for it to be moved.
Having said all that, you've probably got a corrupt framework or a hardware fault. Flash a fresh official stock rom after a factory reset to test. If it's still the same then send for repair.
Is this when in a call sorry to ask noob question just curious if your covering the proximity sensor

Screen Blanks out on Galaxy tab
I ran this test and your screen is only supposed to change color from white to green during the test. My screen blanks out completely during the test.
Not sure if the sensor is bad or if it is a software or and OS issue yet.
you tube.c om /watch?v=N8G6ksaciho
Need advice.
I just received a SM-T705Y, KitKat. When I am in only some applications not all, the screen shuts completely off when my finger passes over the two sensors/camera near the word "SAMSUNG" at the top of the device. I have tested the cause and done it repeatedly by putting a small piece of black electrical tape on the sensor.
With the tape on the sensor, the screen never shuts off. The screen then will come back on several seconds after I remove my finger/tape from the sensor. Also, I do not have to actually touch the sensor to get the screen to turn off. But it activates the lock screen when it does turn off. ANNOYING !!!
My SM-T705Y is not rooted. It is in developer mode.
I think its the sensor that turns the screen off when you take a phone call is still stuck on ???
I have the phone proximity sensor turned off in: Settings> When I'm the phone screen The screen stays on.
Auto adjust screen tone : ON
Auto brightness is off
I have the "Smart Stay" turned off in: Settings>Device>Display.
Screen timeout set to 10 minutes. Screen mode set to "AMOLED Cinema"
I have restarted, not rebooted the SM-T705Y

The proximity sensor is located there. That's why you have that issue. It's normal behaviour.
If you are trying to turn the screen off during calls there is an option to do so in either calls settings or display settings.
If you move the phone away from your head it will turn the screen on. It's a proximity sensor, thats its job!.
Beamed in by telepathy.
Fix
I have same problem with my samsung and I fix it!
Just close all recently used app (press button next to menu button and close all) and you will have normal screen..... Looks like some app, especially call app make problem and activating proximity sensor. So one more time close all recently used app, press button next to menu button and close all app....
Good Luck!

[Q] LG G2 D802 problem when making or answering a call

Hi guys.I have a problem with my LG G2 D802.When I answer a call or make a call,the screen goes blank and the touch doesn't work anymore.I can't do anything else on the phone.The conversation is normal and anything else seems to be ok.Please help! Thank you.
If I answer a call,the screen goes blank,I can speak normally:After the call even the other person finishes the conversation,I still can't do anything on the phone,because the screen stays blank.If I have another call this will awake the screen and it will work normally,I mean,I can take the call,answer and speak on the phone but with the screen blank again. and so on.To have the phone back to normal,I have to reboot it by switching the phone off and on again. Very strange.This happened after I unlocked the phone ,probably because I left the SIM card in ?!!! Any possible advice/solution? I tried soft and hard/factory reset with no results.

I actually had this same issue. my g2 is rooted, but running the stock rom. it has a screen protector but nothing else that would impede the sensors.
I found that this issue never took place in well lit areas. but if at night sitting i a poorly lit room I would go to swipe the scree it would unlock for a second or two and then lock back up. in talking with a friend. I found that the g2 has in set so in the proximity of a pocket or something dark the screen dims back so as to not allow you to mistakenly hit ay button ( i.e. butt dial) i figured my proximity sensor near the ear piece was dirty and causing much less light then there actually was. at the time there wast a firmware update ( which I have now gotten) and was desperately seeking help.
I finally got the firmware update VS98012B and it seems to have solved the issue I ( and you) was having. I would see what version you are running now and then update to the aforementioned and see if that solves your problem.
PM me and let me know what road you decide to travel and if for some reason it doesn't help you we shall figure it out.
Blank Screen
I am having sort of the same issue. But mine is wether in a well lit room or dark room it doesn't matter.
I noticed that it usually happens when i receive a call, after the conversation when i hang up it does not go back to the home screen. all i get is a blank screen. the only way i can get it to generate the home screen again is by pulling down the status bar and going into the general settings and clicking home button again.
during this blank screen i can still see the status bar, and when i bring down the status bar i can see the nav buttons but they are unresponsive.
I also noticed this takes place sometimes after closing an app (noticed on netflix)
I am rooted on stock rom and TWRP recovery. Phone Model [LS-980 Sprint]
I immediately rooted so dont know if issue was there before root.
SOMEONE PLEASE HELP.

I decided to open the phone and check the proximity sensor.I unplugged the proximity sensor ribbon and guess what:IT WORKS.without the functions of the proximity sensor and LED.But at least,I have the keypad and the screen on during a conversation.I have even the knock-knock function.Probably,I will use it like that until a kit-kat update will be available.Thanks for your answer.
VS980 Black Screen
I have a customer phone that I replaced the LCD and Digitizer on. The new screen works fine but...now when a SIM Card is in the phone and I dial out a thin horizontal line appears in the middle of the screen and then the screen goes black.
If I remove the SIM card and place a call, the phone gives me the standard "Emergency Calls Only" and goes back to the dial pad.
The SIM Card is not activated but it is recognized by the phone.
Has anyone else had this issue? I tried a factory restore with no luck.

Hi,
I have the same issue , my screen turns black when calling or receiving calls , i m not really good with my hands... so do you know other solutions to disable the proximity sensor ?
thanks
Same issue here - LG G2 screen turn off and goes blank during conversations
I have exactly the same issue - LG G2 D802 screen turn off and goes blank during conversations.
Thanks to @Bam9 and @EtherBoo , who suggested to clear the proximity sensor from the outside and squeeze the top left corner of the phone, I tried to clean it and put some stress on it - and it worked!
Another issue which I also have and is also caused by the proximity sensor is that the screen stays on and the touch buttons in the dialer aren't responsive - which means we can't switch to speaker, add a call, mute, etc... However, the main touch / navigation button (home, back and menu buttons in the bottom of the screen) are responsive, in addition to the status bar.
(This issue was already reported by @athorax here)
In both of these situations the only quick way to end a call is to pull down the status and notifications bar and hang up from there.
I have a glass screen protector (which don't block the proximity sensor), and I am rooted and using CyanogenMod 11 ROM.
I used ioroot to root and AutoRec, which comes with TWRP 2.7.0.0, to install CyanogenMod ROM.
However, going back to stock ROM (in my case, LG G2 D802, it's D80220C) won't help since the issue still exists.
What I'm sure is that it was pretty much okay in the beginning, and the situation became worse and worse - occurring randomly, until it arrived to a situation in which I can't use the phone properly during conversation.
Now that I discovered that I can put some stress on the proximity sensor it seems that I have a hardware rather than a software issue.

So for you it was a software issue?
Is your sensor working until today with no issues?

I'm also rooted and with TWRP.
Did it happened before you rooted?
Did you used ioroot to root andAutoRec to have TWRP?
You see, I'm really trying to find the similarities between us all in order to solve this issue...

We already have KitKat based firmware update. For me it's D80220C.
For you it might be already D80220D. Use this link to check your version, and replace the IMEI in the end of it with your IMEI.

When you place the call you do hear that the call is made?
If so - then you have exactly the same issue.
What is your model, what ROM are you using, and did you root your phone?
I have LG G2, unable to make call. The signal strength is fine. I have tried reinserting the sim. but i am able to receive calls. when i make a call the dialup screen come up and call ended automatically. Any Help
